This is due largely to the greater action of bentonite on colloidal color material found in younger wines (Bergeret 1963). Fining certain red wines with 1/2 to 1 pound of bentonite per 1000 gallons is said to enhance merane filterability.

Aluminum oxide | Al2O3 - PubChem

Calcium is a silvery white metal. The surface of calcium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium

Carbide - Wikipedia

2019-4-13 · Several carbides are assumed to be salts of the acetylide anion C 2 2– (also called percarbide), which has a triple bond between the two carbon atoms. Alkali metals, alkaline earth metals, and lanthanoid metals form acetylides, e.g., sodium carbide Na 2 C 2, calcium carbide CaC 2, and LaC 2. Lanthanides also form carbides (sesquicarbides, see below) with formula M 2 C 3.
